Answer:
An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess.
<span>Maggie's training regimen may put her at risk to develop secondary amenorrhea. While amenorrhea is the absence of menstruation, secondary amenorrhea is the absence of the menstrual cycle in females who have started menstruating (having had at least one cycle) and then stop menstruating for a period longer than three months. Secondary amenorrhea occurs in times of extreme stress or weight loss (such as anorexia). Female soldiers have experienced secondary amenorrhea when they have gone to war or have become prisoners of war. Hormone shots, extreme weight gain, birth control, and certain medications also cause the condition.</span>
<u>Answer:</u>
<em>The two major processes by which bacterial populations produce genetic diversity are gene transfer and mutation.</em>
<u>Explanation:</u>
Gene transfer in bacteria occurs through conjugation. In the process of conjugation, the plasmid gets transferred from bacteria to another. Mitosis leads to the formation of two identical individuals.
In this process, the chromosome and the DNA content of the daughter cell remains the same as the mother cell. Bacteria also divides by the process of binary fission.
The scientists who provided this hypothesis had an idea that the species evolved in order to accommodate their needs on certain islands. For instance, an example is beak size of certain birds which Darwin thought that this was to eat certain foods.
This has something to do with winter seasons. You see, during winter days, <span>the sun is further down in the sky, so the same circle of sunlight covers a wider area, so there is less light per plant. In this case, those plants that are pointing straight at the sun have higher chances of growing better. Hope this answers your question.</span>
